NGAMBRI GRINDING GROOVES VIDEO
Grinding grooves are stone artifacts created by Aboriginal people by the action of grinding stone on stone to facilitate the sharpening of stone implements. The following post relates to a fine example in Tuggeranong.
I shot some video yesterday on a walk to Tuggeranong Hill at Theodore, part of the Canberra Nature Park system of reserves. A short way from everyday suburbia sit sentinel Aboriginal stone artifacts lying as testimony to the original owners of this land we call the Australian Capital Territory. The Ngambri.
The video is of the different stone slabs and the varying types of grooves scattered over them mixed up with my theory of the grooves possibly being formed by a series of different processes or stages of grinding to a singular item (eg axe). But then again maybe the grooves were formed manufacturing several different items. One to ponder...
For more information on Theodore's grinding groves I have an older post here.
